Komunitné fórum Firefox

I'm filling out an appcation for a study permit in canada. My university website said that i should download adobe acrobat reader and use it to open the application pdf. I didn't want to pay for adobe, so i opened it with firefox instead. In the document, there are tab selections that it allows so you can select answers accurate to you and fill out the document. But at the top of the document it says I should enable javascript by going to preferences, then edit, and and then reopen the form. How can I enable javascript in firefox? I'm having difficulty finding the preferences and edit sections.

I have looked at some of the comments about Firefox automatically opening pdf docs. Myu concern is twofold. Most importantly the password in the doc is somehow being overriden; that is a severe security issuen for me. Destroys the whole concept of security. Makes me very uncomfortable and may discontnue using Forefox after more than 15 years. Secondly this caught me by surprise; it only occurred for the first time this morning. How can i overcome this to prevent Firefox from performing merely as a browser?

When I try to select some object on a pdf page, a little window appears with "select" and "comment", and the window blocks other objects of the page. How to remove that forever? That is very inconvenient.

How to download a pdf without secure download ? I thought windows defender was the problem, but I can download a pdf without cleaning it with chrome.

My tax return declaration is made using a spreadsheet like pdf document, and when downloading it with firefox, the cleaned document cannot be filled in.

I use Firefox as my default program for opening PDFs. But if I try to open more than one at the same time it will always leave one out and instead open a "New Tab" that I don't need. Can't figure out why or how to fix it.

Example: If I check (windows 11) files A, B, C, D, and E. It will open A, B, D, & E and a "New Tab" and leave out C.

Any Solutions?

idk, what i did, but i assume it's most likely user error. but i don't even know where to go from where i'm at.

ok, i'm going to attempt to identify what is happening. [guess] .pdf website previews are messing up the font when converting the .pdf to an image asset for the website to use as a current web asset, when the .pdf is updated. (makes sense really, smart drag & drop update of a .pdf menu, has instruction to make the end users browser do the work for you. kind of a one and done webpage coding for older guys that can't type, let alone edit Html, or even use Wix. some people just don't "compute" hard R or not. lol )

i don't even know where to start. i mean Mozilla is probably referencing it's own "lib.moz" which is just probably it's own personal link to an existing Lib file so it can pull it in and do what it needs to do with it without Root etc.

that is probably working fine as it renders (opens) the .pdf fine whence it's downloaded it. so all that i've talked about might not be the problem.

there is probably some mozilla function calling that to convert the .pdf as an image web asset so that it can show a preview of the current .pdf available for download.

that converter is messing up the font recognition, and building a preview image with messed up font characters (why it looks like Wing-Dings). but i don't even know where to start, and i don't think a new install will solve this (kinda overkill, and any residual files may still remain.)

i'm adding a fastfetch

Mozilla Firefox 152.0.1 " updates are manage by your operating system."

re-posted from; [[Why is Firefox PDF printing so strange?|https://support.mozilla.org/en-US/questions/1275786#answer-1276068]] and edited: reasons; support ticket gudelines [[Posting support requests|https://support.mozilla.org/en-US/kb/mozilla-support-rules-guidelines#w_subjects-covered-in-the-support-forum]]

[[i somewhat found an "answer" though i'd hardly call that "solved."|https://support.mozilla.org/en-US/questions/1275786#answer-1276068]]

i still say a Lib in a repo needs updated, within, or perhaps up stream of the project to reflect "commonly used fonts" if applicable (i know that's the trick, 'is it FOSS') yet other browsers use it, though idk if they're FOSS... i'd need to know what i'm looking for to confirm that or not, and do something about that (again most likely upstream, as the PDF Viewer is probably it's own project (or even several), retooled by Mozilla for Firefox.

I am currently revising for professional qualifications and the PDF study manual I am using is extremely large.

I have seen tutors be able to use the document outline on the left sidebar to be able to filter through different chapters.

However, I do not have that option - I only have the option to view page-by-page which is not very helpful.

How can I get the document outline to show a chapter-by-chapter outline?

Well, there is a bug with your downloading files configurations that REALLY ANNOYS me, which is, i want to always select where to save my downloaded files, no problem with that, i just set all configurations to "always ask", but sometimes, especially for pdfs, i want to just open them, without the need to save them to my computer, so the only one i have set as "open with firefox" is the pdfs, and if i want to download them, i just do so by clicking the download button on the corner. BUT, with this configuration, if there is a button to download a pdf, without opening it previously, it will skip the "ask where to download" pop-up, which is a pain in the ass, as usually want my stuff in specific folders, not the general downloads one. And even iff i set pdfs to "always ask" and then chose to open with firefox, it will automatically download it (???????) to the downloads folder, and then open it from my pc, even tho it could open it from the file in the server, which is what i wanted. I just switched to firefox, please fix this awful feature and dont make me find another browser.

In the past, I was able to freehand highlight PDFs that did not recognize the Text. I was using this function this week; maybe the newest Firefox update is at fault. Without this, half of my documents are not really usable in Firefox. Everything else works. If it recognizes the text, I have no problems; the pencil tool also works just fine.

1. Have read some recent questions which are similar. 2. My current Firefox is 151.04 (64 bit) I use Windows 11 Home 3. My problem relates to payroll in QuickBooks and has only occurred for payroll run after 20th May 2026. PDF's for payrun dated 20th May 2026 open with no problem. Any payroll reports after that date fail.

     I download payrun report and the page in firefox browser tab shows a 0 of 0 display (not the normal report)

      The file is sitting in browser download, as well as my C drive file explorer under 'downloads'

      When I double click, or highlight and select open, or highlight and select open with - my SodaPDF app displays a message indicating it failed to open a file.

4. Queried QuickBooks who believe it is a compatibility error.

5. Queried app provider (Soda PDF) and have been doing checks with them, but not able to resolve at this time.

6. Last resort went into QuickBooks using Microsoft Edge - file opened in SodaPDF with no problem.

As my preference is Mozilla browser, would like to have resolved ASAP, otherwise I need to use another browser. Await your advice - Kind regards

Since this morning, Firefox previews any PDF I click on, and then I have to manually download it for it to open in Acrobat. Acrobat is set as my system default. I have tried other suggestions found here, such as going into the troubleshooting and checking the folder profile, but nothing works. It is very frustrating.

I read Firefox's suggestion to use the browser to edit pdf's and thought I'd give it a try, thinking I might be able to use it instead of my old Adobe Acrobat editor.

But I immediately noticed that there's no way to draw a shape with the Firefox pdf editor - a circle for example. The Help says I can select shapes from the Draw menu but the only thing that appears on my Draw menu is a line (see the attachment).

What am I doing wrong?
